Yes, you are right, Sparta Prague cannot be underestimated because they have fought hard to beat Galatasaray with an aggregate of 6-4, Sparta beat a club that was relegated from the Champions League and that is a very good achievement as we all know Galatasaray's strength is of course greater if we compare it with a club like Sparta. Sparta Prague was defeated in the first leg with a score of 3:2 and in the second leg Sparta was able to score more goals and more than Galatasaray scored so Liverpool have to be wary of this club because they could put quite a lot of pressure on Liverpool in the first leg and hopefully Liverpool can keep their defense tight.

The match between Brighton vs Roma can indeed be said to be quite difficult, even though Brighton itself is a Premier League club which Roma certainly cannot take lightly. While Roma themselves when facing Feyenoord seemed to have a little difficulty and if it weren't for the penalty Roma might not have qualified for the match. Even though its the same club on average I prefer Brighton in this match to win because it seems like they are more favourites.
